microscopic vs macroscopic cross section

He explains: “A microscopic cross section looks like brickwork, with flat, hexagonal tablets of a crystalline, calcium carbonate mineral stacked in neat layers. jw The distinction between macroscopic and microscopic cross - section is that the former is a property of a specific lump of material (with its density), while the latter is an intrinsic property of a type of nuclei.

Quantifying radiation damage can be done by analyzing the neutron microscopic and macroscopic cross sections of the materials. The cross sections express the likelihood of an interaction between

microscopic cross-section, σ ; probability. of a specified interaction or reaction between an incident radiation and a target particle or system of particles. It 

While the microscopic cross-sectionconveysinformationabout the probabilities ofscattering, absorption orfission for an individual nucleus, the calculation ofthe rates ofthese processes for the reactor as a whole involves, in addition. the numbers of atoms ofeachmaterial perunit volume ofthereactor.

While the macroscopic cross-section represents the effective target area of all of the nuclei contained in the volume of the material. The units are given in cm-1. A macroscopic cross

the microscopic cross sections for thermal neutrons. The cross sections averaged over the thermal neutron energy spectrum, /2 V /2A.

In this study, the total thermal neutron macroscopic and microscopic cross sections of V, Co, Cu, In, Dy and Au were measured using neutron self-absorption.

The coherent and incoherent parts of the elastic scattering cross section are The corresponding microscopic cross sections are obtained as σc = 4π bc.

To compare between actual and generated microscopic cross-section images of hardwood species, we used a VTT based on Park et al. ( ) and Chuquicusma et al. ( ). Our VTT experiments were conducted by a group of eight wood anatomy experts divided into two levels of expertise for analysis of microscopic wood images, namely, four intermediate

Figure 9 shows the variation of Sha factors with neutron energy for Pu microscopic cross sections for spherical particles for all 40 combinations of D and α. A 

The cross section per H2O molecule is 3*0.039 = 0.117 barn. Similarly for heavy water (D2O) with bD = 6.671 fm, one obtains σc(D2O) = 5.12 barn. The cross section per D2O molecule is 3*5.12 = 15.35 barn. 4. INCOHERENT SCATTERING AND DISORDER SCATTERING CROSS SECTIONS Every element in the periodic table has a spin incoherence scattering cross

Famous quotes containing the words section, cross and/or microscopic: “ Ah, Governor [Murphy, of New Jersey], don’t try to deceive me as to the sentiment of the dear people. I have been hearing from the West and the East, and the South seems to be the only section which approves of me at all, and that comes from merely a generous impulse, for even that section
